Out of curiosity, if I had multiple DMB files that all had the same RSC (basically, different instances of the same game), and I link()ed between them, would a player have to redownload the RSC? I ask because in the sense of my (planned) RPG, there will be 3 DMBs each compiled with different maps, but all will have the same RSC file (not the exact one, they'll be in different folders).

No, resources should not have to be redownloaded in this case. Let us know if they are, though, as we've had some issues (hopefully since resolved) in this department.
